Ebenso ist es üblich, an und in Gebäuden eine Wärme- oder Schalldämmung vorzusehen.To the Protection against excessive heat or sonic loads become built-in parts, body parts, etc. in automobiles and aircraft with insulating panels fitted. It is also common on and in buildings a heat or soundproofing provided.

Beispielsweise an der Stirnwand im Motorraum oder im Bereich des Getriebetunnels von Kraftfahrzeugen ist eine Verkleidung mit Schichten aus Fasern, Mineralwolle (5 bis 20 mm), Metallfolie (50 bis 500 μm), Textilfaservlies (5 bis 40 mm) und gegegebenenfalls Deckvlies gemäß DE 197 20 537 A1 vorgeschlagen worden. Als Bindemittel für die Vliesstoffe werden unter anderem Polyproyplen, Polyethylen und/oder Ethyl-Vinylacetat-Copolymere angegeben. Die Schichtdicke der jeweiligen Schichten kann dabei den jeweiligen Erfordernissen angepasst werden. Die Gesamtdicke dieser Verkleidung ist üblicherweise 10 bis 40 mm.For example, on the front wall in the engine compartment or in the area of the transmission tunnel of motor vehicles is a cladding with layers of fibers, mineral wool (5 to 20 mm), metal foil (50 to 500 microns), textile fiber fleece (5 to 40 mm) and, where appropriate, cover fleece according DE 197 20 537 A1 been proposed. Polypropylene, polyethylene and / or ethyl-vinyl acetate copolymers are specified as binders for the nonwovens. The layer thickness of the respective layers can be adapted to the respective requirements. The total thickness of this panel is usually 10 to 40 mm.

In der DE 200 04 796 U1 ist ein bahnen- oder plattenförmiges Schalldämmelement mit einer Schicht aus Kohlefasern oder anderen akustisch wirksamen Werkstoffen beschrieben, auf dessen Oberfläche eine Sperrschicht aus thermoplastischem Werkstoff, isnbesondere aus Polypropylen, angeordnet ist. Diese Schichten können mit einem zusätzlichen Schalldämmmterial aus geschäumtem oder Vlieswerkstoff kombiniert sein, das mit einer Selbstklebeausrüstung für die Montage versehen ist.In the DE 200 04 796 U1 a sheet or plate-shaped sound insulation is described with a layer of carbon fibers or other acoustically active materials, on the surface of a barrier layer of thermoplastic material, isnbesondere made of polypropylene, is arranged.

Zur Wärme- oder Schallisolierung beispielsweise in Flugzeugen ist eine Isolierdecke vorgeschlagen worden, die im wesentlichen frei von Glasfasern ist. Sie liegt vorzugsweise in Form einer Vliesmatte mit thermoplastischen Fasern vor. Thermoplastisches Polyolefin, beispielsweise Polyethylen, Polypropylen, Ethylen-Propylen-Copolymer oder einer Kombination davon, dient als äußere Umhüllung für eine gute Beständigkeit gegenüber der Aufnahme von Feuchtigkeit. Im Inneren befinden sich eine Isolierschicht aus Fasern oder Schaum, die als Verbund mit einer hochtemperaturfesten Schicht aus Keramik, Glasfasern vorgesehen werden kann.to Warmth- or soundproofing, for example, in airplanes is an insulated ceiling has been proposed which is substantially free of glass fibers. It is preferably in the form of a nonwoven mat with thermoplastic Fibers before. Thermoplastic polyolefin, for example polyethylene, Polypropylene, ethylene-propylene copolymer or a combination of it, serves as an outer serving for a good resistance across from the absorption of moisture.

Der Erfindung liegt die Aufgabe zugrunde, ein Isolierelement zu schaffen, das keine Flüssigkeiten aufnimmt oder durchlässt, schwer entflammbar und selbst verlöschend ist und auch mit größeren Dämmschichtdicken wirtschaftlich einsetzbar ist.Of the Invention has for its object to provide an insulating element, that no liquids absorbs or lets through, is flame retardant and self extinguishing and also with greater insulation thicknesses is economically usable.

Diese Aufgabe ist durch die Erfindung bei einem Isolierelement mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen des Isolierelements sind Gegenstand der Unteransprüche.These Task is by the invention in an insulating with the Characteristics of claim 1 solved. Advantageous developments of the insulating are the subject the dependent claims.

Ein Isolierelement gemäß der Erfindung besteht somit aus einer außen liegenden Schicht aus höher wärmebeständigem geschlossenporigem Schaumstoff und einer dieser benachbarten innen liegenden Schicht aus geringer wärmebeständigem geschlossenporigem Schaumstoff, die mit einander verbunden sind.One Insulating element according to the invention thus consists of an outside lying higher layer heat-resistant closed-cell foam and one of these adjacent inner layers is smaller heat-resistant closed-cell Foam, which are connected to each other.

Dieses Isolierelement zeichnet sich somit auf der Außenseite mit einem Material aus, dass die erforderliche Temperaturbeständigkeit für die dort herrschenden Umgebungsbedingungen aufweist. Außerdem nimmt dieses Material keine Flüssigkeiten wie z.B. Wasser auf und erfüllt auch die häufig gestellte Bedingung, dass keine Flüssigkeiten eindringen sollen (Penetrationsprüfung z.B. nach UNE 53-335-78 Parte V [Diesel]). Zusammen mit beispielsweise dem Karosserieblech bildet es eine schwer entflammbare und selbst verlöschende Schutzschicht.This Insulating element is thus characterized on the outside with a material from that the required temperature resistance for the prevailing environmental conditions having. Furthermore this material does not absorb any liquids such as. Water up and up also the common ones condition that no liquids should penetrate (Penetration testing e.g. to UNE 53-335-78 Parte V [Diesel]). Together with example The body panel makes it a flame retardant and self extinguishing Protective layer.

Auf der Innenseite kann ein Material vorgesehen sein, das eine geringere Wärmebeständigkeit hat und damit kostengünstiger ist. Die Dicke des auf der Außenseite liegenden Materials mit der höheren Wärmebeständigkeit ist dabei so gewählt, dass der Temperaturabfall ausreichend bis auf Temperaturen an der Unterseite ist, die den Spezifikationen des auf der Innenseite befindlichen Materials entsprechen. Abgesehen von dieser Bedingung können die Gesamtdicke des Isolierelements und die einzelnen Schichtdicken entsprechend den jeweiligen Erfordernissen variiert werden. Ohne weiteres kann das Isolierelement beispielsweise mit einer Dicke von 70 mm eingesetzt werden, ohne dass dies einen Grenzwert für die Dicke darstellt.On the inside of a material may be provided, which is a lesser Has heat resistance and thus cheaper is. The thickness of the outside lying material with the higher heat resistance is chosen that the temperature drop sufficient up to temperatures at the Bottom is that the specifications of the located on the inside Match material. Apart from this condition, the Total thickness of the insulating element and the individual layer thicknesses be varied according to the respective requirements. Without Furthermore, the insulating element can be made, for example, with a thickness of 70 mm, without this being a limit to the thickness represents.

Vorzugsweise sind die beiden Schaumstoffschichten miteinander laminiert. Als Material für die beiden Schaumstoffschichten können beispielsweise Polyolefine eingesetzt werden, z.B. außen Polypropylen und innen Polyethylen.Preferably the two foam layers are laminated together. When Material for For example, the two foam layers can be polyolefins can be used, e.g. Outside Polypropylene and inside polyethylene.

Es kann je nach Einsatzfall zweckmäßig sein, dass die Schicht aus höher wärmebeständigem Schaumstoff und/oder die Schicht aus weniger wärmebeständigem Schaustoff mehrlagig ist.It may be appropriate, depending on the application, that the layer of higher heat-resistant Foam and / or the layer of less heat-resistant Schaustoff is multi-layered.

Bei einer vorteilhaften Ausführungsform des erfindungsgemäßen Isolierelements ist die Schicht aus höher wärmebeständigem Schaumstoff auf der Außenseite mit einer wärmereflektierenden Folie, insbesondere Metallfolie, versehen. Diese strahlt bereits einen wesentlichen Teil der Wärme zurück, so lediglich ein Teil der vorherrschenden Temperaturen über die Schichten des Isolierelements abgebaut werden muss. Ist die Außentemperatur nicht so hoch oder eine Rückstrahlung der auftreffenden Wärmestrahlung nicht erforderlich, kann die wärmereflektierende Folie entfallen.at an advantageous embodiment the insulating element according to the invention the layer is higher heat resistant foam on the outside with a heat-reflecting Foil, in particular metal foil provided. This already radiates a significant part of the heat back, so only part of the prevailing temperatures over the Layers of insulating must be dismantled. Is the outside temperature not so high or a reflection the incident heat radiation not required, the heat-reflecting Foil omitted.

Als Folienmaterial wird vorzugsweise Metall, insbesondere Aluminium, verwendet. Die wärmereflektierende Folie ist zweckmäßig auf die Schaumstoffschichten auf kaschiert.When Foil material is preferably metal, in particular aluminum, used. The heat-reflecting Foil is functional on the foam layers laminated on.

Es kann auch vorgesehen werden, alternativ zu einer wärmereflektierenden Folie einen anderen Werkstoff, wie z.B. Kohlefaservlies, auf die Außenseite der Schaumstoffschicht mit höherer Wärmebeständigkeit aufzubringen.It can also be provided, alternatively to a heat-reflecting Foil another material, e.g. Carbon fiber fleece, on the outside the foam layer with higher heat resistance applied.

Während auch andere Befestigungsmöglichkeiten wie Klemmen und Spannen möglich sind, kann auf der Innenseite des Isolierelements für die Befestigung beispielsweise an einer Fahrzeugkarosserie eine Befestigungsfolie vorgesehen sein. Diese ist vorzugsweise selbstklebend. Vorteilhaft ist es, sie aufzukaschieren. Sie kann aber je nach den Anforderungen an das Isolierelement auch entfallen.While too other attachment options like clamping and clamping possible are, on the inside of the insulating element for attachment For example, on a vehicle body, a mounting film be provided. This is preferably self-adhesive. Advantageous is to put it on. It can however depending on the requirements also account for the insulating.

In der Zeichnung ist ein Ausführungsbeispiel eines erfindungsgemäßen Isolierelements veranschaulicht. Dieses umfasst je eine Schicht aus höher und geringer wärmebeständigem Schaumstoff, die außen eine wärmereflektierende bzw. zur Befestigung dienende Folie tragen.In The drawing is an embodiment of a Insulating element according to the invention illustrated. This includes one layer each of higher and higher low heat-resistant foam, the outside a heat-reflecting or for fixing serving foil wear.

Im einzelnen: Das Isolierelement weist auf der den erhöhten Temperaturen bzw. Lärmpegel zugewandten Seite (Außenseite) eine wärmereflektierende Folie 1 auf, bei der es sich im vorliegenden Beispiel um eine Aluminiumfolie handelt. Die Aluminiumfolie 1 ist auf die Schicht 2 aus höher wärmebeständigem Schaumstoff auf kaschiert.In detail: The insulating element has on the side facing the elevated temperatures or noise level (outside) a heat-reflecting film 1 which is an aluminum foil in the present example. The aluminum foil 1 is on the layer 2 made of higher heat-resistant foam on laminated.

Die Schaumstoffschicht 2 ist beim gezeigten Ausführungsbeispiel zweilagig. Die beiden Lagen 2a und 2b sind zusammen laminiert. Die Schaumstoffschicht 2 ist aus Polypropylen.The foam layer 2 is two layers in the embodiment shown. The two layers 2a and 2 B are laminated together. The foam layer 2 is made of polypropylene.

Unter der Schaumstoffschicht 2 befindet sich die zweite Schaumstoffschicht 3, die jedoch weniger wärmebeständig ist. Sie ist wiederum zweilagig und ihre beiden Lagen 3a und 3b sind zusammen laminiert, ebenso die beiden Schaumstoffschichten 2 und 3. Die Schaumstoffschicht 3 ist aus Polyethylen.Under the foam layer 2 is the second foam layer 3 which, however, is less heat resistant. She is again two-ply and her two layers 3a and 3b are laminated together, as are the two foam layers 2 and 3 , The foam layer 3 is made of polyethylene.

Auf der Innenseite, also gegenüberliegend zur Aluminiumfolie 1, ist die Schaumstoffschicht 3 mit der erwähnten Befestigungsfolie 4 versehen. Diese ist selbstklebend.On the inside, so opposite to the aluminum foil 1 , is the foam layer 3 with the mentioned fastening film 4 Mistake. This is self-adhesive.

Der Aluminiumfolie kann somit ein kleiner Temperaturgradient zugeordnet werden, wie der Abschnitt a des Temperaturdiagramms veranschaulicht. In der Schaumstoffschicht 2, die von den beiden Schaumstoffschichten die höhere Wärmebeständigkeit hat, nimmt die Temperatur von außen nach innen ab, wie der Abschnitt b des Temperaturdiagramms zeigt. Im Abschnitt c des Temperaturdiagramms, der den Temperaturverlauf in der zweiten Schaumstoffschicht 3 veranschaulicht, nimmt die Temperatur über die Schichtdicke ebenfalls, aber mit geringerem Gradienten, ab. Der Temperaturgradient über die Befestigungsfolie 4 ist klein, wie der Abschnitt d des Temperaturdiagramms zeigt.The function of the insulating element according to the invention is as follows, as described in the 2 Integrated temperature diagram is illustrated. The ordinate represents the temperature T (° C) and the abscissa the thickness of the layers. The aluminum foil 1 reflects a part of the heat radiation striking the surface. This is illustrated by the arrows A. Part of the heat is through the aluminum foil 1 derived, as also indicated by an arrow. The aluminum foil can thus be assigned a small temperature gradient, as illustrated in section a of the temperature diagram. In the foam layer 2 , which has the higher heat resistance of the two foam layers, decreases the temperature from outside to inside, as shown in section b of the temperature diagram. In section c of the temperature diagram, the temperature profile in the second foam layer 3 The temperature across the layer thickness also decreases, but with a lower gradient. The temperature gradient over the fastening film 4 is small, as the section d of the temperature diagram shows.
